AAW AXH Universal-Fit IEM

Advanced AcousticWerkes is well loved among the Massdrop community for its CIEM offerings, which include the A3H Pro. Now, the company continues its streak of top-notch hybrid in-ear monitors with the AXH: a universal-fit IEM that combines a 10-millimeter proprietary dynamic driver with four balanced-armature drivers. By using TrueXross technology, this model addresses the crossover problems of many multiple-driver IEMs, which lead to chaotic phase shift and scrambled arrival timing. The dynamic driver has an individually tuned diaphragm, and by utilizing a physical low-pass filter, it functions in a minimal overlapping frequency range as opposed to the balanced-armature driver. Pairing delicate positional arrangement and a new copper acoustic bore design, AAW achieves improved coherence, minimized phase shift, and optimized arrival timing of the music signal. 

One reviewer says, “Overall, it's a very coherent sound that excels in technicalities, especially in its price range. I think AAW has managed to improve vastly upon the original tuning and created an earphone that is able to hold its weight and some, and at its price versus specs, I feel it's really good value and would be a good neutral IEM that isn't sterile.”
